6. Sting
Sting's repeated, nearly annual negotiations with WWE have been highly speculated and publicized for years, with it finally looking like the two may come to a working relationship this year. Perhaps the closest the two sides got was in 2011, when the Undertaker return segments that aired apparently being originally intended for Sting, whom was still negotiating with WWE. Ultimately Sting decided against coming to the WWE for the fantasy matchup with the Undertaker, and would instead return to TNA for three more years. Sting mentioned that a primary reason he decided against going to the WWE in the past was what he perceived to be a disrespectful promo between The Rock and former WCW champion Booker T. During the promo the Rock seemingly dismissed all of Booker T and WCW's accomplishments by pretended he had no idea who Booker was. Sting said that promo resonated with him, and he feared doing damage to the WCW legacy, as well as his own if he were to enter the WWE.
